I had no idea, which tells you how much I've had the tv on. It's been such a long, hard slog since the writer's strike, I barely remember how it ended, although I believe I was distraught over the fate of Nathan. Also, I recall that Peter needed to stop being stupid and that the Irish girl needed to be permanently lost in the future.
Queue it up, people. I'm going to need to hash this out later.
AFTER VIEWING: Whoa. That was awesome x 2.
